HORSESHOE.

SPECIFICATION forming part of Letters Patent No. "710,618, dated October '7, 1902.

Application filed June 10, 1902. Serial No. 111,063. (No model.)

To (all whom i2; may concern:

3e it known that I, FRED A. SCHLEPPY, a citizen of the United States, residing at Lattimer Mines, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Horsehoe, of which the following is a specification.

This invention relates to horseshoes, and more particularly to that class in which removable calks are employed.

In the construction of shoes now generally used the bodies thereof are provided with screw-threaded openings and the calks have threaded shanks which are screwed into the openings. \Vhile it is comparatively easy to remove these calks before they are worn down flush with the face of the shoe, it often happens through carelessness or oversight that they are thus worn, in which event the method, as suggested by the manufacturers and generallyfollowed, is to remove the shoe, heat it, then punch out the shank, and afterward rethread the opening. It will be evident that this is rather an expensive operation that consumes considerable time, besides including the necessity of removing the shoe from and replacing it upon the horses hoof.

The aim of the present invention is to overcome all these objectionable features by the combination of a calk and shoe which are relatively constructed so that a tool may be readily applied to the calla-even when it is worn down flush with the'face of the shoe, thereby avoiding the necessity of carrying out the method above described. The construction whereby these results are accomplished is shown in the accompanying drawings, wherein- Figure 1 is a bottom plan view of a horseshoe constructed in accordance with the present invention and showing the calks applied thereto. Fig. 2 is a perspective view of a portion of the shoe, illustrating the calks when worn down. Fig. 3 is a cross-sectional view through Fig. 1. Fig. 4 is a perspective View of the preferred form of tool employed in removing the calks. Fig. 5 is a sectional view through the same.

Similar numerals of reference designate corresponding parts in all the figures of the drawings.

The body 10 of the shoe is of the usual shape, but is provided in its outer face with a plurality of circular sockets 11, these sockets being located at the points where the calks are applied, and therefore two being preferably arranged at the toe of the shoe and one contiguous to each heel. Threaded openings 12 extend from the bottoms of these sockets through the shoe, these openings being arranged concentric with the socket, but of much less diameter. As the openings and counterbores or sockets can be made simultaneously, it will be evident that the expense of this construction is no greater than that of forming the usual openings in the shoe.

The calks employed com prise threaded shanks 13, which are screwed into the openings 12, and tapering heads 14:, which project beyond the outer face of the shoe, these heads being preferably, though not necessarily, pyramidal in form. They are provided with rectangular bases 15,which are located within the sockets when the calks are in place and are spaced from the walls of said sockets a sulficient distance to permit the insertion of a suitable removing-tool. This tool is preferably in the form of a wrench 16, having springjaws 17, connected at their upper ends, the lower ends having coacting seats 18,that form an angular socket to receive the bases 15 of the calks. An adjusting-screw 19 connects the lower portions of the jaws, being provided with a suitable thumb-piece 20, whereby said screw may be operated. The wrench is also provided with a cross-handle 21, secured to its upper end.- The outer face of the lower end of the wrench is circular in form and is designed to fit in the sockets 11 of the shoe.

In use the calks are fastened in place, as already described and shown in Fig. 8, the shanks being threaded in the openings 12 and the heads projecting from the face of the shoe. It will be seen, therefore, that when these calks are worn down flush with the face of the shoe the angular bases will remain, as they are seated within and protected by the sockets. The calks can therefore be readily removed by cleaning out the sockets, inserting the tool over the angular bases remaining, and rotating said tool. Furthermore, this can be accomplished without the necessity of removing the shoe from the horses hoof. It will therefore be evident that this particular combination has decided advantages over the prior art. These advantages arise from the use of the angular bases 15, which are spaced a sufficient distance from the walls of the sockets 11 to permit the insertion of a removing-tool that will engage about said bases.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

A horseshoe having a socket in its outer face and a screw-threaded opening extending from the bottom of the socket and of less diameter than the same, in combination with a calk having a threaded shank that is screwed into the opening of the shoe, and an angular base fitted in the socket below the plane of the face of the shoe, said angular base being spaced from the walls of the socket a sufiicient distance to permit the insertion of a tool in-said socket and in engagement with the base.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
